Check the power plug and the power socket as often as possible.
Electrical/power socket must be secured, and also proper
grounding must be provided. The power plug and the power
socket must not heat excessively.
If the water heater is not used for a long time, especially in the
area with low air temperature (below 0
o
C), it is necessary to drain
the water from the heater to prevent damage, due to water-
freezing in its internal tank (refer to the “Cautions” chapter in this
manual book for the method of draining away the water from the
inner container/tank).
To make the water heater durable, it is recommended to regularly
clean the internal tank and remove deposits on the electric
heating element of the water heater, as well as check the
condition of the magnesium anode (whether fully decomposed or
not) and, if necessary, replace it with a new one in case of full
decomposition. Tank cleaning frequency depends on the hardness
of the water in each location where this water heater is applied.
Cleaning must be performed by
MODENA
or special maintenance
services. Contact
MODENA
Customer Care if necessary.
The water heater is equipped with a thermal switch, which cuts off
the power supply of the heating element upon overheating water
or the absence of water in the water heater. If the water heater is
connected to the power supply (electricity), but the water is not
heated and the indicator does not light up, then the thermal
switch was off or not switched on. To reset the water heater to
the normal operating condition, it is necessary to:
1.
De-energize the water heater; remove the plate of the
side/lower cover.
2.
Press the button that is located at the center of the thermal
switch
PART 5: MAINTENANCE
WARNING!
Do cut off the power supply before maintenance in order to
avoid danger like electric shock.
